2) CHECK OF ALL CONTROL ELEMENTS, LEVERS AND PEDALS FUNCTIONING. Visual check first, then manual
check with the machine off. Check that everything is fixed correctly, without unusual clearance, clean,
greased and ready to be used for work operations. All control elements are explained in
functioning of the control elements also with the engine on, in a test area, before transferring the machine
and starting to work.
3) ROTOR WASHING using the supplied hose holder: screw
it in their seats on the deck sides, fix the water hose and
fasten it with a band. Open the jet, step on the machine
and, while starting the engine, engage the rotor so it can
be properly washed while it is turning. Note: pay the utmost
attention: object projection and exhaust gas inhalation
hazard. These operations must be performed outdoors,
making sure to keep the deck in its lowest position. Repeat the operation on the opposite side. Remember
to remove the sleeve before starting to work!!!
4) INSPECTION OF ROTOR BLADES and their possible replacement (use
work gloves!). Keep in mind that:
- A single blade must be replaced with a new one when it is broken,
bent or worn.
- All blades must be replaced (with their fixing bolts) every 50 hours as
specified in Chap. 7d
IN CASE OF ABNORMAL VIBRATIONS, COMPLETELY REPLACE
ALL THE BLADES AND RELATED BOLTS
